title: Role of balloon postdilation following trancatheter aortic valve implantation.
abstract: Paravalvular aortic regurgitation (AR) is a frequent complication following transcatheter aortic valve implantation (TAVI) with an incidence of mild to moderate AR almost systematically higher than 30%. Moreover, several studies have shown that AR has a negative impact on short and mid-term mortality. Balloon postdilation has been proposed as an initial periprocedural option for patients with paravalvular AR to obtain a better expansion of the stent valve frame and potentially reduce the severity of the leak. The aim of this review is to discuss the current available literature on balloon postdilation as a treatment of paravalvular AR after TAVI, its impact on clinical events and future perspectives.
